Abstract
Description
Die Erfindung betrifft einen Schwingungsdämpfer für ein Fahrzeug nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a vibration damper for a vehicle according to the preamble of claim 1.
Schwingungsdämpfer für Fahrzeuge weisen üblicherweise einen fahrzeugaufbauseitigen Aufprallpuffer aus Polyurethan oder Gummi auf. Dieser kommt bei stärkerem Einfedern der Radaufhängung an dem Dämpferrohr des Schwingungsdämpfers zur Anlage und fängt so als Zusatzfeder zusammen mit einer Tragfeder Schwingungsamplituden des Dämpferrohrs des Schwingungsdämpfers auf.Vibration damper for vehicles usually a vehicle body side impact buffer made of polyurethane or Rubber on. This comes with stronger Suspension of the suspension the damper tube of the vibration damper to the plant and catches so as an additional spring together with a suspension spring vibration amplitudes the damper tube of the vibration damper on.
Aus
der
Insbesondere bei Fahrzeugen mit sportlich ausgelegtem Fahrwerk soll die Zusatzfeder im normalen Fahrbetrieb ausreichend steif gestaltet sein.Especially in vehicles with sporty suspension designed the auxiliary spring be designed sufficiently rigid in normal driving.
Andererseits soll die Zusatzfeder einen ausreichend großen Einfederweg bereitstellen. Der große Federweg gewährleistet, dass große, stoßartige Kräfte aufgefangen und in Schwingungen umgewandelt werden. Bei einer Schwellenüberfahrt können daher Beschädigungen am Fahrwerk des Fahrzeugs vermieden werden. Nachteilig ist jedoch, dass für einen großen Federweg die Zusatzfeder mit einer großen Federhöhe zu dimensionieren ist, wodurch im normalen Fahrbetrieb die Zusatzfeder zwangsläufig im weicheren Kennlinienbereich mit geringerer Federrate arbeitet.on the other hand the auxiliary spring should provide a sufficiently large compression travel. The great Ensures travel, that big, impulsive forces intercepted and be transformed into vibrations. At a threshold crossing can therefore damage be avoided on the chassis of the vehicle. The disadvantage, however, is that for a big Travel the auxiliary spring is to be dimensioned with a large spring height, which In normal driving, the additional spring inevitably in the softer characteristic range works at a lower spring rate.
Die Aufgabe der Erfindung besteht darin, einen Schwingungsdämpfer für ein Fahrzeug bereitzustellen, der im normalen Einsatzbereich ausreichend steif ist und bei Sonderereignissen, etwa einer Schwellenüberfahrt, zugleich einen ausreichend großen Federweg bereitstellt.The The object of the invention is a vibration damper for a vehicle to provide sufficient stiffness in the normal field of use and for special events, such as a threshold crossing, at the same time a sufficiently large Provides travel.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The The object is solved by the features of claim 1. advantageous Further developments of the invention are disclosed in the subclaims.
Gemäß dem kennzeichnenden Teil des Patentanspruches 1 ist die Zusatzfeder mit zumindest einem weiteren Federelement in Reihe geschaltet. Durch die Reihenschaltung der Zusatzfeder mit dem Federelement kann die Federcharakteristik der Fahrwerksfederung insgesamt in einfacher Weise variiert werden. Hierzu kann eine herkömmlich ausgebildete Zusatzfeder mit dem Federelement einfach in Reihe gekoppelt werden.According to the characterizing one Part of claim 1 is the additional spring with at least one another spring element connected in series. Through the series connection the additional spring with the spring element can the spring characteristic the suspension suspension can be varied in a simple manner. This can be a conventional trained additional spring with the spring element simply coupled in series become.
In einer besonderen Ausführungsform kann die Zusatzfeder unter Zwischenschaltung des Federelements an einem aufbauseitigen Tragelement abgestützt sein. In diesem Fall ist die Zusatzfeder also nicht unmittelbar an dem steifen aufbauseitigen Tragelement oder dergleichen angebunden, sondern mittels des Federelements federnd am Tragelement abgestützt.In a particular embodiment can the additional spring with the interposition of the spring element be supported on a body-side support member. In this case is the additional spring so not directly on the rigid body side Supporting element or the like connected, but by means of the spring element resiliently supported on the support element.
Um die Federkennung der Fahrwerksfederung den spezifischen Anforderungen des jeweiligen Fahrzeugs anzupassen, ist es vorteilhaft, wenn das Federelement und die Zusatzfedern unterschiedliche Federsteifigkeiten aufweisen. Dabei kann es insbesondere bei einer sportlichen Auslegung des Fahrwerks bevorzugt sein, wenn das Federelement auf eine Vorspannkraft vorgespannt ist. Bei einer Krafteinleitung in den Schwingungsdämpfer unterhalb der Vorspannkraft entspricht somit das Federelement einer steifen Abstützung ohne Federeigenschaft. Erst wenn der Schwingungsdämpfer mit einer Kraft belastet wird, die größer als die Vorspannkraft ist, kann das Federelement einen zusätzlichen Federweg bereitstellen.Around the spring rate of suspension suspension to the specific requirements adapt the respective vehicle, it is advantageous if the spring element and the additional springs have different spring stiffnesses. It may be particularly in a sporty interpretation of the chassis be preferred when the spring element is biased to a biasing force is. For a force introduction into the vibration damper below the biasing force thus corresponds to the spring element of a stiff support without spring characteristic. Only when the vibration damper with loaded with a force greater than the preload force, the spring element can be an additional Provide travel.
Erfindungsgemäß kann die Zusatzfeder mit einer geringeren Länge dimensioniert werden, wodurch die Federrate der Zusatzfeder im normalen Fahrbetrieb in den steifen Bereich der Federkennlinie der Zusatzfeder verlagert ist. Wenn etwa bei einer Schwellenüberfahrt des Fahrzeugs die in den Schwingungsdämpfer eingeleitete stoßartige Kraft die Vorspannkraft des Federelements übersteigt, so kann der Dämpfer aufgrund des vorgespannten Federelements weiter einfedern. Das Federelement stellt somit einen zusätzlichen Federweg für einen zusätzlichen Kraftabbau bereit. Der aufgrund einer reduzierten Federhöhe der Zusatzfeder fehlende Federweg kann somit durch das vorgespannte steife Federelement zurückgewonnen werden.According to the invention, the Additional spring can be dimensioned with a shorter length, which the spring rate of the auxiliary spring in normal driving in the stiff Area of the spring characteristic of the additional spring is shifted. If about at a threshold crossing of the vehicle introduced into the shock absorber shock-like Force exceeds the biasing force of the spring element, the damper due to continue to spring in the prestressed spring element. The spring element provides thus an additional Travel for An additional Power reduction ready. The due to a reduced spring height of the auxiliary spring Missing travel can thus by the prestressed stiff spring element recovered become.
Vorteilhaft ist es dabei, wenn die Vorspannkraft des Federelements einer Kraft entspricht, bei der sich die Zusatzfeder bereits im progressiven, nicht linearen Kennlinienbereich befindet. In diesem Fall ist gewährleistet, dass das Federelement erst bei einem Sonderereignis außerhalb des normalen Fahrbetriebs einen zusätzlichen Federweg zum Kraftabbau bereitstellt und im normalen Fahrbetrieb ohne Federeigenschaften ist.Advantageous it is when the biasing force of the spring element of a force corresponds, in which the auxiliary spring already in progressive, not linear characteristic area is located. In this case, it is ensured that the spring element only outside a special event the normal driving an additional suspension travel for power reduction provides and in normal driving without spring characteristics is.
Um eine kompakte Bauweise der aus der Zusatzfeder und dem Federelement bestehenden Anordnung zu ermöglichen, kann das Federelement ein Tellerfederpaket mit äußerst geringer Bauhöhe sein. Als Zusatzfeder kann ein herkömmlicher Anschlagpuffer aus einem Elastomermaterial eingesetzt werden.Around a compact design of the additional spring and the spring element to allow existing arrangement The spring element may be a disc spring package with extremely low height. As additional spring can be a conventional one Stop buffers are used made of an elastomeric material.
Um baulich in einfacher Weise die Federcharakteristik der Fahrwerksfederung einzustellen, können die Zusatzfeder und das Federelement zwei separate Bauteile sein, die in einfacher Weise gegeneinander austauschbar sind. Die Zusatzfeder und das Federelement können zur Bildung einer kompakten Baueinheit in einem zum Dämpferrohr offenen Gehäuse gelagert sein. Dabei kann das Federelement zwischen einem Gehäuseboden und einer Sperrscheibe im Gehäuse auf eine vorbestimmte Vorspannkraft gespannt werden. Zur Einstellung der Vorspannkraft des Federelements kann die Sperrscheibe höhenverstellbar im Gehäuse angeordnet sein. Die Höhenverstellbarkeit der Sperrscheibe kann in einfacher Weise über eine Schraubverbindung zwischen der Sperrscheibe und dem Gehäuse realisiert werden. In diesem Fall kann die Sperrscheibe zur Höhenverstellung lediglich in das Gehäuse hineingeschraubt oder aus dem Gehäuse herausgeschraubt werden.Around structurally simple way the spring characteristic of the suspension suspension can adjust the additional spring and the spring element are two separate components, which are easily interchangeable. The additional spring and the spring element can to form a compact unit in a damper tube open housing be stored. In this case, the spring element between a housing bottom and a locking disc in the housing be stretched to a predetermined biasing force. To adjustment the biasing force of the spring element, the locking disc height adjustable in the case be arranged. The height adjustment the locking disc can easily via a screw be realized between the locking disc and the housing. In this Case, the locking disc for height adjustment only in the case screwed in or unscrewed out of the housing.
